Monitor REST and SOAP APIs 24x7

API Availability, Performance and Functional Correctness

APIs are taking the world by a storm. As you strive to deliver world class web, mobile and SaaS applications, make sure the APIs that power them are running smoothly.

AlertSite makes it easier than ever to monitor your internal, partner, or public APIs - REST or SOAP - effortlessly.  Create an API endpoint monitor natively in AlertSite, or reuse OpenAPI/Swagger definitions and SoapUI tests to monitor complex API transactions where APIs need to be invoked in sequence with the appropriate set of contextual data. 

  • Go Beyond Simple Endpoint Check
  • Get Alerted to Performance Anomalies
  • Monitor Around the Globe and Behind the Firewall
  • Start with Existing OpenAPI/Swagger Defintions or SoapUI Tests

Ensure Complete API Quality - Not Just 200 OK

  • Just checking the API endpoint is responsiveness is not enough when your applications depend on APIs. AlertSite helps you test the functionality, performance, correctness, and speed of the API call.
  • Easily create advanced API monitors right from the dashboard, or simply by reusing your existing OpenAPI/Swagger defintions or SoapUI functional tests.
  • Monitor chained API transactions where APIs need to be invoked in sequence, and contextual data needs to be passed from one call to the next.

Increase Agility for DevOps Teams and CICD Initiatives

Monitor the Public or Partner APIs you Consume

  • You may not be providing APIs, but it is highly likely that your consuming them daily.  Services such as location or mapping are common third-party APIs that you might use.
  • What happens to your business if they are unavailable, slow or incorrect? Monitor the 3rd party APIs you consume and verify that they are returning right data every time. 
  • Detect API issues early on and hold your API vendors accountable.


Monitor Internal APIs and Web Services

  • Microservices and APIs are critical part of modern applications. Slow or dysfunctional internal APIs affect your internal applications and decelerate innovation.
  • Monitor internal APIs that serve your internal customers from within your private network using our private nodes placed in your local network, data center, or private cloud. 
  • Monitoring APIs continually throughout the CI cycle and detect and fix issues early on, aiding to continuous deployment and DevOps initiatives.
